Patent number: 7095040Abstract: An electron-emitting device includes an electron source layer made of a metal, a metal alloy or a semiconductor, an insulating layer formed on the electron source layer and a metal thin film electrode formed on the insulating layer. Electrons are emitted upon application of an electric field between the electron source layer and the metal thin film electrode. The insulating layer has at least one island region which constitutes an electron-emitting section in which the film thickness of the insulating layer is gradually reduced. The electron-emitting device further includes a carbon region made of carbon or a carbon compound on at least one of a top, bottom and inside of the island region.Type: GrantFiled: January 4, 2001Date of Patent: August 22, 2006Assignee: Pioneer CorporationInventors: Shingo Iwasaki, Takashi Yamada, Takuya Hata, Takashi Chuman, Nobuyasu Negishi, Kazuto Sakemura, Atsushi Yoshizawa, Hideo Satoh, Takamasa Yoshikawa, Kiyohide Ogasawara

Publication number: 20050151480Abstract: An image display device includes at least one transmissive display panel arranged at different depth positions in a direction normal to a display surface of the image display device. Each of the transmissive display panels includes a light-emitting layer that is sandwiched between a front side transmissive film and a rear side transmissive film. The rear side transmissive film has an interface with a maximum refractive index difference that causes an efficiency of light emitted from the light-emitting layer to become smaller than a front side light emission efficiency in the characteristics of light-emission efficiency, which changes with respect to a film thickness of the transmissive film due to optical interference.Type: ApplicationFiled: September 19, 2003Publication date: July 14, 2005Inventors: Atsushi Yoshizawa, Takashi Chuman, Takuya Hata, Yoshihiko Uchida, Hideo Satoh, Shuuichi Yanagisawa
